Review Unbelievable rude !!!

I cancelled my ADT on the 22 February 2018, for end of March 2018, end of April the debit order goes off again, I have reversed the debit order. In the mean time I got married and moved to Vanderbijlpark, selling my house. Now ADT keep harassing me for payment, I have send all the proof that I have canceled several times. Yesterday a man called me demanding to give him my date of birth yelling at me, I could not speak to him as he keep yelling at me to give my date of birth. I ended the call. This harassment is unacceptable, SHAME ON ADT!!!!!!!!!!!, so rude then you have to protect us NO NO NO NO, stay away
